What Food Can Possums Not Eat? A Comprehensive Guide
The answer to what food can possums not eat? isn’t a simple list, but rather a nuanced understanding of their digestive systems, preferences, and the potential dangers of certain substances. Possums generally avoid toxic or rotten food, and are known to have issues processing dairy, chocolate, or processed human foods.
Understanding the Possum Diet
Possums are opportunistic omnivores, meaning they eat almost anything they can find. In the wild, their diet consists primarily of insects, fruits, nuts, eggs, small rodents, and carrion. However, their opportunistic nature means they often scavenge for food in urban environments, leading to encounters with food sources that aren’t necessarily good for them. Understanding their natural diet helps clarify what food can possums not eat.

Food Avoidance: Toxicity and Taste
While possums aren’t particularly picky, they do exhibit some aversion to certain foods. This aversion is often based on taste, smell, or perceived toxicity. It’s important to remember that while they might try something, that doesn’t mean it’s good for them.
-
Toxic Plants: Many plants are poisonous to possums, including nightshade, foxglove, and azaleas. They generally avoid these plants, but young or inexperienced possums may accidentally ingest them.
-
Spoiled Food: Possums are scavengers, but they usually avoid heavily spoiled food that is obviously rotten. The risk of bacterial contamination is likely a deterrent.
-
Certain Spices: Extremely spicy foods might deter possums, although this isn’t a guarantee. Strong flavors can be off-putting.
The Dangers of Processed Foods
One of the biggest concerns for possums in urban environments is the availability of processed human food. This type of food often lacks the necessary nutrients for a healthy possum diet and can contain ingredients that are actively harmful.
-
Chocolate: Like dogs, possums are susceptible to theobromine poisoning from chocolate. The darker the chocolate, the more toxic it is.
-
Dairy Products: Possums are generally lactose intolerant. Dairy products can cause digestive upset, including diarrhea and dehydration.
-
Processed Foods: These are often high in sugar, salt, and unhealthy fats. They provide little nutritional value and can lead to obesity and other health problems.
-
Dog and Cat Food: While possums will readily eat pet food, it’s not ideal for their nutritional needs. It is too high in protein and fat, and lacks some essential nutrients possums need.
Water: An Essential, Often Overlooked Need
While not technically food, access to clean water is crucial for possum survival. Dehydration can be a significant problem, especially in hot weather. Providing a shallow dish of water can be beneficial, but ensure it’s clean and changed regularly.
Feeding Possums: Best Practices
It’s generally recommended not to intentionally feed possums. Providing a consistent food source can make them dependent on humans and disrupt their natural foraging behaviors. If you feel compelled to help, focus on providing a safe environment and access to clean water.
Comparing Unsafe Foods for Possums
| Food Item | Reason for Avoidance | Potential Health Effects |
|---|---|---|
| ————— | ———————————- | ———————————— |
| Chocolate | Theobromine toxicity | Seizures, heart problems, death |
| Dairy Products | Lactose intolerance | Diarrhea, dehydration, malnutrition |
| Processed Foods | High sugar/salt/fat, low nutrients | Obesity, diabetes, organ damage |
| Toxic Plants | Presence of poisonous compounds | Organ failure, death |
Frequently Asked Questions (FAQs)
What is the most important thing to remember about feeding possums?
The most important thing to remember is that it’s generally best not to intentionally feed possums. Providing a consistent food source can make them dependent on humans, alter their natural behaviors, and potentially lead to overpopulation in certain areas. Focus on removing attractants and providing access to water if needed.
Are there any specific fruits or vegetables that possums should avoid?
While possums eat many fruits and vegetables in the wild, avoid giving them fruits with pits, such as cherries or peaches, as the pits can be toxic. Also, be cautious with raw potatoes, as they contain solanine, which can be harmful.
Can possums eat bread?
Although a possum might eat bread, it offers very little nutritional value. Bread is essentially empty calories and can contribute to weight gain and other health problems. It’s best to avoid giving them bread.
Is it okay to give a possum milk?
No, it is not okay to give a possum milk. Possums are generally lactose intolerant, meaning they cannot properly digest lactose, the sugar found in milk. Giving them milk can lead to digestive upset, diarrhea, and dehydration.
What should I do if I find a baby possum?
If you find a baby possum, do not attempt to care for it yourself. Contact a licensed wildlife rehabilitator. They have the knowledge and resources to properly care for orphaned or injured possums and give them the best chance of survival.
Will possums eat poison intended for rodents?
Unfortunately, possums can be unintentionally poisoned by consuming rodenticides (rat poison). Rodenticides are designed to be palatable to rodents, and possums may ingest them either directly or by eating poisoned rodents. This highlights the importance of using rodent control methods that are safe for non-target species.
Are possums immune to snake venom?
Possums have some resistance to snake venom, but they are not completely immune. Their blood contains a protein that can neutralize some snake venoms, providing a degree of protection. However, a bite from a venomous snake can still be dangerous and require veterinary attention.
What attracts possums to my yard?
Possums are attracted to yards with readily available food sources, such as unsecured garbage cans, pet food left outside, fallen fruit, and accessible compost bins. They are also attracted to areas that offer shelter, such as dense vegetation, woodpiles, and under decks or sheds.
How can I deter possums from my property?
To deter possums, secure your garbage cans with tight-fitting lids, bring pet food indoors at night, clean up fallen fruit, and enclose compost bins. You can also trim back vegetation to reduce hiding places and consider using motion-activated sprinklers or lights.
What is the average lifespan of a possum?
In the wild, possums typically live for 1-2 years. In captivity, with proper care, they can live longer, sometimes up to 4 years. Their lifespan is often limited by predation, disease, and environmental factors.
Do possums carry diseases that are harmful to humans or pets?
Possums can carry various parasites and diseases, including leptospirosis, tuberculosis, and coccidiosis. While the risk of transmission to humans or pets is generally low, it’s important to practice good hygiene and avoid direct contact with possums. Pet owners should keep their animals vaccinated and dewormed.
Why are possums sometimes seen during the day?
Possums are primarily nocturnal, but they may be seen during the day if they are sick, injured, or have been disturbed from their resting place. They may also be seen during the day if they are particularly hungry or if food is scarce. Seeing a possum during the day is not necessarily cause for alarm, but if the animal appears distressed, contact a wildlife rehabilitator. Knowing what food can possums not eat and their general behaviours will improve chances of coexisting.
